Thanks, but actually no change is required there, since when running the
tests, we're guaranteed to be using coreutils' own version of "head".
By contrast, the just-fixed use in init.sh had no such protection, since
init.sh is used in other projects.

However, if you'd like to adjust your patch to make the test
use head -n99 instead (more readable than sed 99q and more future-proof
than "head -99", in case we stop supporting head -N), I'll apply it.
